Installation with pip (and easy_install) fails

[bnsblue]

This is what I got from the installation through pip (and easy_install):

I tried to look for png.h, and it looks like it is indeed missing in the downloaded tarball

Dou you have Matplotlib installed? The error above seems to be an error of installing matplotlib. Actually, I think I saw this error before, but I cannot remember how to solve it right now. :(

If you do not have matplotlib installed, you might want to try to install it first with your distribution's package manager.

Hi, thank you for your fast reply!I have matplotlib and the other prerequisite installed on my Ubuntu already, and it was installed via apt-get. I am actually able to use matplotlib to generate (not-so-pretty) graphs...Any suggestions?:)Thank you!Sent from AcompliOn Thu, May 22, 2014 at 8:44 AM -0700, "Jan Gosmann" notifications@github.com wrote:

Thank you for your comment. Unfortunately, I no longer have the bandwidth to maintain prettyplotlib. I recommend using seaborn. Using seaborn, to get the prettyplotlib style, do:

import seaborn as sns
sns.set(style='ticks', palette='Set2')

And to remove "chartjunk", do:

sns.despine()

If you have discrete pull requests, I will accept them, but I personally will no longer fix bugs.
